Study information
Scientific title
Acronym
Effect of Myfortic® on UV-induced DNA-damage and atopic status
Study hypothesis
Our hypothesis is that in patients with atopic dermatitis which use topical tacrolimus 0.1% the repair of DeoxyriboNucleic Acid (DNA)-damage in the skin is delayed. The repair of DNA-damage in the skin of patients with atopic dermatitis which use a class II corticosteroid is not delayed.

Condition
Atopic dermatitis
Intervention
Ten patients in total with atopic dermatitis are to be included in the study. The inclusion takes place after the physician has indicated that treatment with oral immunosuppressive drugs is necessary. The informed consent intake will be performed by the researcher. At inclusion a screening will be done to evaluate the severity of the eczema and the atopic state (total and specific Immunoglobulin E [IgE], skin-prick test and atopy patch test) of the patient.
Subsequently we will compare UV-irradiated, non-lesional skin prior to treatment (control) to UV-irradiated, non-lesional skin treated with Myfortic® during 12 weeks (intervention). The Minimal Erythema Dose (MED) will be determined prior to actual irradiation. Punch biopsies will be taken immediately after irradiation with two MED and after 24 hours. A reference biopsy will be taken from skin that is not irrradiated. The whole process will be repeated after 12 weeks of treatment.
To evaluate the atopic status after 12 weeks of treatment, we will repeat the skin-prick test and atopy patch test. The final clinical evaluation of therapy will be performed after 16 weeks.

Myfortic®
Primary outcome measure
The difference between the percentage in repair of Cyclobutane Pyrimidine Dimers (CPD's) before and after treatment with Myfortic® is the primary study outcome.
Secondary outcome measures
1. The atopic state before and after treatment with Myfortic®.
2. The evaluation of the efficacy of initial high dosing with Myfortic® in order to induce rapid improvement of the disease.
